To begin your positive tone business letter, you could start with a professional greeting such as "Dear [Company Name],".

Then, you can express your appreciation using positive language. For example, you could say something like, "I wanted to take a moment to express my gratitude for the quality products and excellent customer service that your company consistently provides."

Next, you can mention the specific issue you are addressing, which is the out-of-stock luggage merchandise that Mrs. Smith at the store informed you about. You can state this in a clear and straightforward manner, such as, "I recently visited your store and was informed by Mrs. Smith that the luggage merchandise I was interested in is currently out of stock."

Lastly, you can transition into explaining your purpose for writing the letter. In this case, it could be to inquire about the availability of the luggage merchandise or to explore alternative options. You can use positive language to convey your intentions, for example, "I am writing to inquire about the availability of the out-of-stock luggage merchandise or to explore any alternative options you might have."

Remember to maintain a positive tone throughout the letter, as it will help maintain a good relationship with the company and increase the likelihood of a positive response.
